Physics- Please help and give quick explanation!
A simple pendulum & a mass on a spring each have a period of 2.0 seconds on Earth. They are then taken to another planet (one without a pandemic). The new planet has the same diameter as Earth but a much greater mass. Which of the statements correctly describe the periods for the pendulum & mass on spring on the virus-free planet as compared to the earth? *
Answers:
Both periods are shorter on the new planet.
Both periods are the same on the new planet.
Both periods are longer on the new planet.
The period for mass on spring is shorter on new planet, period of pendulum is the same.
The period of pendulum is shorter on new planet, period of mass on spring is the same.
